Summary
Elevation data can often provide a complete data set for analysis and derivative products without any other data. In this chapter we learned to:
Read/write ASCII Grids using only NumPy
Create shaded reliefs, slope grids, and aspect grids
Create elevation contours
Transform LIDAR data into a grid
Visualize LIDAR data with PIL
Create a TIN
In the next chapter we'll combine the building blocks from the previous three chapters to do some advanced modeling and actually create some information products.
